Spectrum-dose conversion operators, G(E) functions of NaI(Tl) scintillators adapted for effective dose equivalent quantities

G(E) functions of spectrum-dose conversion operators are shown for eight kinds of NaI(Tl) scintillators for various radiation quantities. The G(E) function method evaluates dose directly from an observed gamma-ray pulse-height spectrum with ease and high accuracy. Dimensions of the considered detectors are 1''φ x 1'', 2''φ x 2'', 3''φ x 3'', 4''φ x 4'', 5''φ x 4'' for cylindrical type and 2''φ, 3''φ, 5''φ for spherical type. For radiation quantities, four kinds of kermas, four kinds of 1 cm depth dose equivalents in the ICRU sphere, and effective dose equivalents calculated with a numerical human phantom under five irradiation geometries are considered. The energy range of gamma-rays is 50 keV to 10 MeV. The detector response functions calculated by a Monte Carlo simulation code, MARTHA were used to derive G(E) functions. (author)
